TO WHOM I'll MAY CONCERN:

Be it known that I, JAMES A. MGRRELL, of Chicago, in the county oi'Cook, and State of Illinois, have l invented an Improved Hinge; and I dohereby declare that the following is a. full and exact description ofthe same, reference being had to the accompanying drawings, and lettersof reference marked thereon, making a part of this specification, inwhichi l Figure I is a perspective representation ol' my improved hinge,including a part of the door orgatc D, and gate or door-post E, to whichthe hinge is supposed to be attached.

Figure II is a longitudinal section of my improved hinge, including alsoa part of the gate or door D anda part ot' the gatc-post E. A Arepresent the under side of the door and jamb.

Figure III is a. top or plan view of the improved wing of my hinge.

The object of my invention is to provide a convenient hinge, by which agate or door may be hung iusuch i a manner as to be adjustable to theinequalities of the frame or opening. i f

To enable others skilled in the art to make and use my inventioxi, Iwillproceed to describe its onstr ction and operation. i

First, I construct the stationary part or wing of the hinge k in Aany ofthe common styles now in usc or i desired, and to this wing, k, at g, Iattach my improved wing, m, by the common joint now in use. '.lol thiswing m are attached two armsz'z', for the purpose of supporting theeccentric B. At o o on the partm is raised a guide, for the purpose ofdirecting the eccentric B, and holdingit in position vertically throughthe guideoo and wing m. Pis a slot. The object of this slot is that,when the scrcwf is put in position to secure the eccentric B, it willallow a. longitudinal motion of the wing or part m. C is a strap,secured to the door or gate at 7L h h lt, in such a manner as4 to allowa longitudinal motion to the part m. i The object of the strapor part` Cis to holdin position the part m, and also to form a shoulder for theeccentric to rest against. The red lines a: :e :c a.' represent theinside and outside circles circumscribing the eccentric B.

The object ci' the eccentric B, iig. 2, is to lessen or increase thedistance between the arms z' i of the wing m and the strap or part C. Itwill be seen that in order-to do this it is only` necessary to revolvethe eccentric B round the screw f as an axis,and the distance betweenthe armsz'z' and the part @will be changed according to the constructionof the eccentric B. It will also be seen that in changing the distancebetween themrms ii and the part C, the distance between `the gate ordoor D and the gate or door-post E will be changed exactly the samedistance. It will be seen by the plan, iig. 3, that the eccentric hasfour bearings, one on cach arm, and two on the wing of the hinge m, at ii and o', forming a plane for the eccentric to rest upon.

Operation.

In order to use my hinge it is rst necessary to secure the stationarywing or part to the post or j amb to i which the gate or door is to behung in the usual manner, as represented by the screws L h, Sac., thenturn the eccentric half way around, using the screwf as an axis, put thestrap or part C over the wing m, as represented at Fig. III, in such amanner as to yallow the edge of the part C to bear against the eccentricB, then secure the part C to the gate or door by means of the screws h hh h, then secure thc eccentric B in its place by means ofthe i screwf,then the hinge is permanently secured.

The adjustment ofthe hinge to suit the settling of the post to whichthcgate is hung, or the gate, is made i by turning the eccentric B halfround upon the s'crewf, as an axis, to correspond with the positionindicated by the red lines z s; 1: x. This will raise the opposite sideoi' the gate.` In caso thc post that supports the gatet catch settlesforthe gate, then turn the eccentric on the upperhingc, which will lowerthe side of the gate that the latch is ppon. Where the settling isslight theeccentric need not be turned more than a'n eighth or fourthot' the distance around. In all cases they can be adjustcdito suit anyordinary settling or sagging of thc gate or post. This improved wing ofthe hinge m can also be attached to the raised joint for thelower hingeof thc gate, making the gate self-shutting, similar to other hinges. p

Having fully described my device, what I claimas my invention, anddesire to secure by Letters Patent, is-

The eccentric B, in combination with the wing ot' the h i'ngc m,substantially as described, and for the pur--` l poses set forth. f
